> Currently, there is an assumption that internode messages whose verb has 
> priority P0 will always fit within a single messaging frame. While this is 
> usually the case, on occasion it is possible that this assumption does not 
> hold. One example is gossip messages during the startup shadow round, where 
> in very large clusters the digest ack can contain all states for every peer. 
> In this scenario, the respondent fails to send the ack which may lead to the 
> shadow round and, ultimately, the startup failing.
>  
> We could tweak the shadow round acks to minimise the message size, but a more 
> robust solution would be to permit high priority messages to be sent on the 
> large messages connection when necessary.
